Application filed May 27,

To all whom it may concern. I Be it known that I, James Peron HARE, of Don Mills Road, Todmorden, in the county of York, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Railway Switches and Crossovers, of which the following is a specification.

This invention relates to improvements in railway switches or turnouts, and my object is to devise a simple and cheap construction in which the expensive frog used where one rail crosses the other will be donexaway with. I

I attain my object by means of the construction hereinafter described and illus trated in the accompanying drawings in which u Fig. 1 is a plan view of a track showlng my improved turn-out construction;

Fig. 2 a side elevation of part of a rail. showing the guard ina lowered position, its

raised position being 'indicatedin dotted l1nes;-;- M Fig. 3 a section on the line a,b in F 1g 2; Fig. 4c a side elevation of the swinging Fig. 5 a cross section through the swinging tongue; and I I .Fig. -6 an enlarged detail of the means for adjusting the locking means for the swingmg tongue. r i I r In the drawings like numerals of reference indicate corresponding parts in the different figures. 1

1 and 2 are the main line rails and 3 and 4 the turnout rails. The main line rail 2 andthe turn-out rail 3 are, however, cut away where they would normally cross one another. In this cut-away space it is usual to insert a frog, which is a very expensive construction even when such frog has not to for the position. To avoid this large expense and also to provide a construction which may be easily replaced if worn or damaged, I makethis space consid erably less in'length and provide therein the swinging tongue 5, which may in its simplest form he merely a bar or piece of rail, but which will preferably be formed asfollows. 6 is a base providedwith inwardly turned flanges'T, Extending down from this base at one end thereof is the pivot pin 8, which ,extendsthrougha ole in the metal plate 10, which plate will be secured to the ties below the end of the base. Extending down- Specification of Letters Patent.

' relative to the switch rails 13 and 14: will Patented Mar. 28, 19 22. 1921-. Serial No. 472,993. r i i wardly from the ing 9 to give the pivot a good hearing. The, end of the pivot pin 8 belowthe bushing will be provided with a hole 11, through which a pin may be passed to prevent the base be ing lifte Between the flanges 7 on the base is slid the tongue 5, which is usually formed of a piece of rail of sufficient length to fill the plate is ail-integral hush- I space between the parts of the rails .2 and 3. a

To prevent the rail creeping endwiseof the 1 base I provide the members 47, which are bolted to the rail and to the base. To prevent theother end of the base 6 being lifted I provide a plate 12 below the ends of the rails 2 and 3, which plate extends beyond said ends into a slot formed in the end of thebase 6. It. will thus be seen that the tongue 5 is perfectly free to swing horizontally into alinement with either of the rails 2 or3, but

the rails is absolutely prevented.

The swinging tongue 5 may begoperated by itself, but I prefer, however, to so arrange it that the same mechanism which operates neously operate the tongue 5.. '15- is the switch stand by means of which the" switch rails 13 and 14 are moved in the usual mannerthrough the link 16 and bar 17 which vertical movement of the tongue also simultaconnects the switch rails 13 and 14. i To the same endof bar 17 as the link 16 is connected a second link 18, to the other-end of which link is pivotally connected one 'end of a bell crank 19 pivoted on a suitable stationary part. To the other is pivotally connected a. divided rod 20, the parts of which are connected by a turnbuckle 21. The other end of this rod is pivotally connected to the one end of an arm 22, the other end of which stationary part. On the same pivot as the arm 22 is pivoted a second arm 23, and adjustable means are provided for holding the arms 22 and 23 in spaced relationship to. one another, such, for example, as thebolt 24 provided with suitable nuts. I The free end of the arm 23 is pivotally connectedvwith one end of a link 25, the other end of which is secured to the swinging tongue 5. I.

It is advisable, however, to for preventing the operation of, thetongue 5 after the end of the train has passed over the points of the switch rails until the end of the train has also passed over the tongue. .I use for this purpose the end of this bell crank is pivoted on a suitable provide means two guard rails I 26which are slidably mounted on supports rod" 28, theother end of which is secured to the outer sides ofthe rails 1 and 4. These guard rails have recesses in their under sides. When the supports arein these recesses the guard rails occupy the position indicated-in iiull lines in Fig. 2, while whenconnected with the lever 29 pivoted intermediate its ends on a suitable stationary part. To the other end of this lever is pivotally connected a link30,'the other end of which is connected with the guard rail 26 mounted on the "track 1. lilxtending from the lever '29 is an'ar'm 31., to whijeh ispivo'tally connected one 'end'oi a link 32','the other end of which vis pivotally connected with oneend of a bell crank 33 i'ulerumcd on a suitable [stationary part. The other end of this'be'll crank 33 is pivotally connected withone end of the link'34, the other end of which is connected with the guard rail 26' on'thetrack i. As will be seenfrom Fig. 3; theguard rails "26 when in raised be while thewheels of an engine or car are 29' intermediate its pivot and position extend partly over the track. It will thus befseen that .should an engine or car'be passing over the track that the guard rails'cannot be raised; Pivoted on thelever the pivot of the link *30 is arod' 35, theiother end of which isslida'bly supported by a member 361. "On the link 25jis mounted the member 37, which is provided with suitable open project to lockthe ton'guc5 when itism alinement with either as: the rails" 2 or 3. As'I prefer to construct my pfarts so that they 'may be used no matter at what angle, within certain limits, at which the tracks 2 ends cross one another, I arrange the member "37 so that the spacing of the openings therein maybe adjusted. Thisis illustrated more particularly in Fig. 6, from which it "will be seen that a slide 38 is mounted'thereon. The member 37 is'provided with a hole89and a slot 40, while the slide38 is provided with a hole 41 and slot 42, the hole39' being opposite the slot hole 4'1 opposite the slot 40. To

'ings into which the endofthe rod 35 may 42" and the adjust '.the slide' 38 longitudinally 0f the member-37, provide a screw as secured in the ended the slide 38-and passing through aihole iarhe end of the member 817; in which it is" he'ldin position "as adjusted bymeans of suitablenutsl -Itw'ill thus be seen rhatif it is necessaryi to increase or reduce thedistarice between the 11016939" and 41, it "ismerelynecessaryto adjust the nuts 4L4 on the set-swa fFrom the construction described it will same, and

ard 15 cannot be operated until the lever 527 isfirst operated to raise the guard rails and release the'rod 35 from engagement with the member 37.

it will also be seen that while the guard rails 26'are in raisedposition that an engine or car cannot be run over the track.

As an additional precaution to prevent the tongue 5 swinging too far in either dimotion, 1 provide the block members 4-5, which are bolted or spiked to a tie under neath. The ends of these block members are shaped to fit between the head and base of the rail and they thus tend to maintain theend of the tongue in proper position. Two further block members l6 are provided at the pivot end of the tongue, and these are also secured and shaped prevent the tongue from being raised out of position.

"It will be seen from the foregoing speci fication that I have devised a construction which will satisfactorily attain the object of my invention asset forth in the-preamble a V-sh'apedrail' member; a swinging tongue base pivoted shaped member a track member re'movably supported on said base a pair of diverging rails one in alinement with each leg of the V-shaped member, the free end of saidjbase with its trackbeing adapted to into alinement with either of the diverging rails; a plate member below the ends'of the diverging rails but extending" beyond the slot to receive said extension.-
